Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony and

others. These applications have difﬁculties working through NAT (Network Address Translation). Special Applications

makes some of these applications work with the DIR-412. If you need to run applications that require multiple connections,

specify the port normally associated with an application in the “Trigger Port” ﬁeld, select the protocol type as TCP or

UDP, then enter the ﬁrewall (public) ports associated with the trigger port to open them for inbound trafﬁc.

The DIR-412 provides some predeﬁned applications in the table on the bottom of the web page. Select the application

QoS Engine

This option is disabled by default. Enable this option for

better performance and experience with online games

and other interactive applications, such as VoIP.

This option will allow your router to automatically determine

the uplink speed of your Internet connection.

This displays the detected uplink speed.

The speed at which data can be transferred from the

router to your ISP. This is determined by your ISP. ISP’s

offer speed as a download/upload pair. For example,

1.5Mbits/284Kbits. Using this example, you would enter

284. Alternatively you can test your uplink speed with a

service such as www.dslreports.com.

This option allows you to select your connection type. Users can select “auto-detect” or choose the xDSL or cable networks

if they know.

This displays if xDSL or another type of frame relay network has been detected. The DIR-412 can detect the network and

the user can conﬁrm this.

SPI (Stateful Packet Inspection, also known as dynamic packet

ﬁltering) helps to prevent cyber attacks by tracking more state per

session. It validates that the trafﬁc passing through the session

conforms to the protocol.

Check the

Enable DMZ

box and specify the IP address of the

computer on the LAN that you want to have unrestricted Internet

communication in the

DMZ IP Address

ﬁeld. Use the drop-down

menu to specify a host that currently has a DHCP lease from the

DIR-412. If this computer has obtained its IP address automatically

using DHCP, be sure to make a static reservation on the

System >

Network Settings

page so that the IP address of the DMZ machine

does not change.

Use this section to create rules that deny or allow trafﬁc from passing

through the device. See the following page for information on how to

create ﬁrewall rules.

A ﬁrewall protects your network from the outside world. The D-Link DIR-412 offers a ﬁrewall type functionality. The SPI feature helps

prevent cyber attacks. Sometimes you may want a computer exposed to the outside world for certain types of applications. If you choose

to expose a computer, you can enable DMZ. DMZ is short for Demilitarized Zone. This option will expose the chosen computer completely

to the outside world.
